Joseph Dahr Jamail, Jr. (born October 19, 1925) is an American attorney and billionaire. The wealthiest practicing attorney in America, he is frequently referred to as the "King of Torts".[2] As of 2011, his net worth was estimated by Forbes to be $1.5 billion, making him the 833rd richest person in the world.

On May 14, 2008, The University of Texas at Austin announced a $15 million gift from Joe Jamail to support the Law School, Nursing School, and the College of Undergraduate Studies. In response to the gift, the university has renamed a large meeting room in the tower building to the Lee Hage Jamail Academic Room.[4]

On May 29, 2008, the Lee and Joe Jamail Skatepark opened near downtown Houston. It was a $2.7 million project. The park is public and covers over 40,000 square feet (3,700 m2).

On April 27, 2011, The San Marcos Baptist Academy announced a $1 million gift from Joe Jamail to help establish a fund to build a special event center on the Academy campus in memory of Jamail’s wife, Lee, who graduated from San Marcos Academy in 1944.[5]

Jamail is known for his passionate, aggressive, sometimes abrasive advocacy on behalf of his clients—a tendency that has been noted in the National Law Journal, by the Supreme Court of Delaware[6] as well as other sources.[7] On its own motion, having reviewed deposition transcripts in the Paramount case, the Delaware Supreme Court referred to Mr. Jamail's conduct as "rude, uncivil and vulgar", "abusing the privilege of representing a witness in a Delaware proceeding", 637 A.2d. 34, at 53, as displaying "an astonishing lack of professionalism and civility", and as "outrageous" and as "unacceptable", for statements to deposing counsel such as "you could gag a maggot off a meatwagon". 637 A2d. 34, at 54. The Court included its admonition of Mr. Jamail in an Addendum to its opinion "as a lesson for the future—a lesson of conduct not to be tolerated or repeated." 637 A2d. 34, at 52. In April 2006, a particularly sharp exchange, titled "Joe Jamail takes a deposition defended by Edward Carstarphen. Hilarity ensues" or "Texas-Style Deposition", appeared[8] on various blogs and internet sites (particularly related to American law). Following a reprimand by the Delaware Supreme Court, Jamail stated in the press "I'd rather have a nose on my ass than go to Delaware for any reason".[9]
